DETAILED DESCRIPTION

A messaging system typically allow users to exchange content items(e.g., messages, images and/or video) with one another in a messagethread. A messaging system may implement or otherwise work inconjunction with an augmented reality system to display augmentedreality content with respect to messaging. For example, the augmentedreality content is combined with image data captured by a device camerain creating message content. However, a user may wish for facilitatedselection of augmented reality content with respect to messaging.

The disclosed embodiments provide for a messaging application running ona device to navigate through augmented reality content items (e.g.,corresponding to applying Lenses or augmented reality experiences) whiledisplaying image data captured by a device camera. For example, themessaging application displays a carousel interface with icons forselecting among available augmented reality content items. The messagingapplication is configured to receive user input of a first type (e.g., adrag gesture), indicating to quickly navigate between the augmentedreality content items. In response, the messaging applicationdiscontinues displaying the carousel interface (e.g., by replacing itwith a sliding interface), and provides for more quickly navigatingthrough the augmented reality content items while continuing to displaythe image data captured by the device camera.

Alternatively or in addition, the messaging application is configured toreceive user input of a second type (e.g., a swipe gesture) indicatingto more slowly navigate between the augmented reality content items. Inresponse, the messaging application provides for more slowly (e.g.,iteratively) navigating through the augmented reality content itemswhile continuing to display the captured image data and continuing todisplay the carousel interface.

FIG. 1 is a block diagram showing an example messaging system 100 forexchanging data (e.g., messages and associated content) over a network106. The messaging system 100 includes instances of a client device 102,each of which hosts a number of applications, including a messagingclient application 104. Each messaging client application 104 iscommunicatively coupled to other instances of the messaging clientapplication 104 and a messaging server system 110 via a network 106(e.g., the Internet).

A messaging client application 104 is able to communicate and exchangedata with another messaging client application 104 and with themessaging server system 110 via the network 106. The data exchangedbetween the messaging client application 104, and between the othermessaging client application 104 and the messaging server system 110,includes functions (e.g., commands to invoke functions) as well aspayload data (e.g., text, audio, video or other multimedia data).

In some embodiments, the messaging client application 104 activates acamera of the client device 102 (e.g., upon startup of the messagingclient application 104). The messaging client application 104 allows auser to request to scan one or more items in a camera feed captured bythe camera. For example, the messaging client application 104 mayreceive a user selection of a dedicated scan option (e.g., a button)presented together with the camera feed. In an alternative embodiment,the messaging client application 104 may detect physical contact betweena finger of the user's hand and a region of the touch screen for athreshold period of time. For example, the messaging client application104 determines that the user touched and held their finger on the screenfor more than three seconds. In response, the messaging clientapplication 104 captures an image being displayed on the screen andprocesses the image to identify one or more objects in the image. Insome embodiments, the messaging client application 104 uses one or moretrained classifiers and/or environmental factors to identify the objectsin the image.

The messaging server system 110 provides server-side functionality viathe network 106 to a particular messaging client application 104. Whilecertain functions of the messaging system 100 are described herein asbeing performed by either the messaging client application 104 or by themessaging server system 110, it will be appreciated that the location ofcertain functionality either within the messaging client application 104or the messaging server system 110 is a design choice. For example, itmay be technically preferable to initially deploy certain technology andfunctionality within the messaging server system 110, but to latermigrate this technology and functionality to the messaging clientapplication 104 where a client device 102 has a sufficient processingcapacity.

The messaging server system 110 supports various services and operationsthat are provided to the messaging client application 104. Suchoperations include transmitting data to, receiving data from, andprocessing data generated by the messaging client application 104. Thisdata may include message content, client device information, graphicalelements, geolocation information, media annotation and overlays,virtual objects, message content persistence conditions, social networkinformation, and live event information, as examples. Data exchangeswithin the messaging system 100 are invoked and controlled throughfunctions available via user interfaces (UIs) (e.g., graphical userinterfaces) of the messaging client application 104.

Turning now specifically to the messaging server system 110, an APIserver 108 (application programming interface server) is coupled to, andprovides a programmatic interface to, an application server 112. Theapplication server 112 is communicatively coupled to a database server116, which facilitates access to a database 122 in which is stored dataassociated with messages processed by the application server 112.

Dealing specifically with the API server 108, this server receives andtransmits message data (e.g., commands and message payloads) between theclient device 102 and the application server 112. Specifically, the APIserver 108 provides a set of interfaces (e.g., routines and protocols)that can be called or queried by the messaging client application 104 inorder to invoke functionality of the application server 112. The APIserver 108 exposes various functions supported by the application server112, including account registration; login functionality; the sending ofmessages, via the application server 112, from a particular messagingclient application 104 to another messaging client application 104; thesending of media files (e.g., graphical elements, images or video) fromthe messaging client application 104 to the messaging server application114, and for possible access by another messaging client application104; a graphical element list; the setting of a collection of media data(e.g., a Story); the retrieval of such collections; the retrieval of alist of friends of a user of a client device 102; maintaining augmentedreality content items; the retrieval of messages and content; the addingand deleting of friends to a social graph; the location of friendswithin a social graph; access to user conversation data; access toavatar information stored on messaging server system 110; and opening anapplication event (e.g., relating to the messaging client application104).

The application server 112 hosts a number of applications andsubsystems, including a messaging server application 114, an imageprocessing system 118, a social network system 120, and an augmentedreality system 124. The messaging server application 114 implements anumber of message processing technologies and functions, particularlyrelated to the aggregation and other processing of content (e.g.,textual and multimedia content) included in messages received frommultiple instances of the messaging client application 104. As will bedescribed in further detail, the text and media content from multiplesources may be aggregated into collections of content (e.g., calledStories or galleries). These collections are then made available, by themessaging server application 114, to the messaging client application104. Other processor- and memory-intensive processing of data may alsobe performed server-side by the messaging server application 114, inview of the hardware requirements for such processing.

The application server 112 also includes an image processing system 118that is dedicated to performing various image processing operations,typically with respect to images or video received within the payload ofa message at the messaging server application 114. In one or moreimplementations, a portion of the image processing system 118 may alsobe implemented by the augmented reality system 124.

The social network system 120 supports various social networkingfunctions and services and makes these functions and services availableto the messaging server application 114. To this end, the social networksystem 120 maintains and accesses an entity graph within the database122. Examples of functions and services supported by the social networksystem 120 include the identification of other users of the messagingsystem 100 with which a particular user has relationships or is“following” and also the identification of other entities and interestsof a particular user. Such other users may be referred to as the user'sfriends. The social network system 120 may access location informationassociated with each of the user's friends to determine where they liveor are currently located geographically. The social network system 120may maintain a location profile for each of the user's friendsindicating the geographical location where the user's friends live.

The messaging client application 104 includes a set of functions thatallows the client device 102 to access the augmented reality system 124.The augmented reality system 124 generates and maintains a list ofaugmented reality content items. The augmented reality content items maycorrespond to augmented reality experiences for supplementing capturedimage data with augmented reality content.

In one or more embodiments, the augmented reality system 124 providesfor determining (e.g., receives) one or more attributes (e.g., a name)of an object. The augmented reality system 124 provides for searchingfor one or more augmented reality content items (e.g., virtual objects)that are associated with the one or more attributes of the object, andfor ranking the virtual objects (e.g., based on the associations andweights assigned to each of the attributes). The augmented realitysystem 124 causes one or more virtual objects or graphical elements ofthe highest ranked augmented reality content item to be presented on topof the captured image.

The application server 112 is communicatively coupled to a databaseserver 116, which facilitates access to a database 122, in which isstored data associated with messages processed by the messaging serverapplication 114. The database 122 may be a third-party database. Forexample, the application server 112 may be associated with a firstentity, and the database 122 or a portion of the database 122 may beassociated and hosted by a second different entity. In some embodiments,the database 122 stores user data that the first entity collects aboutvarious each of the users of a service provided by the first entity. Forexample, the user data includes user names, phone numbers, passwords,addresses, friends, activity information, preferences, videos or contentconsumed by the user, and so forth.

FIG. 2 is block diagram illustrating further details regarding themessaging system 100, according to example embodiments. Specifically,the messaging system 100 is shown to comprise the messaging clientapplication 104 and the application server 112, which in turn embody anumber of some subsystems, namely an ephemeral timer system 202, acollection management system 204 and an annotation system 206.

The ephemeral timer system 202 is responsible for enforcing thetemporary access to content permitted by the messaging clientapplication 104 and the messaging server application 114. To this end,the ephemeral timer system 202 incorporates a number of timers that,based on duration and display parameters associated with a message, orcollection of messages (e.g., a Story), selectively display and enableaccess to messages and associated content via the messaging clientapplication 104. Further details regarding the operation of theephemeral timer system 202 are provided below.

The collection management system 204 is responsible for managingcollections of media (e.g., collections of text, image video and audiodata). In some examples, a collection of content (e.g., messages,including images, video, text and audio) may be organized into an “eventgallery” or an “event Story.” Such a collection may be made availablefor a specified time period, such as the duration of an event to whichthe content relates. For example, content relating to a music concertmay be made available as a “Story” for the duration of that musicconcert. The collection management system 204 may also be responsiblefor publishing an icon that provides notification of the existence of aparticular collection to the user interface of the messaging clientapplication 104.

The collection management system 204 furthermore includes a curationinterface 208 that allows a collection manager to manage and curate aparticular collection of content. For example, the curation interface208 enables an event organizer to curate a collection of contentrelating to a specific event (e.g., delete inappropriate content orredundant messages). Additionally, the collection management system 204employs machine vision (or image recognition technology) and contentrules to automatically curate a content collection. In certainembodiments, compensation may be paid to a user for inclusion ofuser-generated content into a collection. In such cases, the curationinterface 208 operates to automatically make payments to such users forthe use of their content.

The annotation system 206 provides various functions that enable a userto annotate or otherwise modify or edit media content associated with amessage. For example, the annotation system 206 provides functionsrelated to the generation and publishing of media overlays for messagesprocessed by the messaging system 100. The annotation system 206operatively supplies a media overlay or supplementation (e.g., an imagefilter) to the messaging client application 104 based on a geolocationof the client device 102. In another example, the annotation system 206operatively supplies a media overlay to the messaging client application104 based on other information, such as social network information ofthe user of the client device 102. A media overlay may include audio andvisual content and visual effects. Examples of audio and visual contentinclude pictures, texts, logos, animations, and sound effects. Anexample of a visual effect includes color overlaying. The audio andvisual content or the visual effects can be applied to a content item(e.g., a photo) at the client device 102. For example, the media overlaymay include text that can be overlaid on top of a photograph taken bythe client device 102. In another example, the media overlay includes anidentification of a location overlay (e.g., Venice beach), a name of alive event, or a name of a merchant overlay (e.g., Beach Coffee House).In another example, the annotation system 206 uses the geolocation ofthe client device 102 to identify a media overlay that includes the nameof a merchant at the geolocation of the client device 102. The mediaoverlay may include other indicia associated with the merchant. Themedia overlays may be stored in the database 122 and accessed throughthe database server 116.

In one example embodiment, the annotation system 206 provides auser-based publication platform that enables users to select ageolocation on a map, and upload content associated with the selectedgeolocation. The user may also specify circumstances under which aparticular media overlay should be offered to other users. Theannotation system 206 generates a media overlay that includes theuploaded content and associates the uploaded content with the selectedgeolocation.

In another example embodiment, the annotation system 206 provides amerchant-based publication platform that enables merchants to select aparticular media overlay associated with a geolocation via a biddingprocess. For example, the annotation system 206 associates the mediaoverlay of a highest bidding merchant with a corresponding geolocationfor a predefined amount of time.

FIG. 3 is a schematic diagram illustrating data structures 300 which maybe stored in the database 122 of the messaging server system 110,according to certain example embodiments. While the content of thedatabase 122 is shown to comprise a number of tables, it will beappreciated that the data could be stored in other types of datastructures (e.g., as an object-oriented database).

The database 122 includes message data stored within a message table314. An entity table 302 stores entity data, including an entity graph304. Entities for which records are maintained within the entity table302 may include individuals, corporate entities, organizations, objects,places, events, and so forth. Regardless of type, any entity regardingwhich the messaging server system 110 stores data may be a recognizedentity. Each entity is provided with a unique identifier, as well as anentity type identifier (not shown).

The entity graph 304 stores information regarding relationships andassociations between entities. Such relationships may be social,professional (e.g., work at a common corporation or organization),interest-based, or activity-based, merely for example.

The message table 314 may store a collection of conversations between auser and one or more friends or entities. The message table 314 mayinclude various attributes of each conversation, such as the list ofparticipants, the size of the conversation (e.g., number of users and/ornumber of messages), the chat color of the conversation, a uniqueidentifier for the conversation, and any other conversation relatedfeature(s).

The database 122 also stores annotation data, in the example form offilters, in an annotation table 312. The database 122 also storesannotated content received in the annotation table 312. Filters forwhich data is stored within the annotation table 312 are associated withand applied to videos (for which data is stored in a video table 310)and/or images (for which data is stored in an image table 308). Filters,in one example, are overlays that are displayed as overlaid on an imageor video during presentation to a recipient user. Filters may be ofvarious types, including user-selected filters from a gallery of filterspresented to a sending user by the messaging client application 104 whenthe sending user is composing a message. Other types of filters includegeolocation filters (also known as geo-filters), which may be presentedto a sending user based on geographic location. For example, geolocationfilters specific to a neighborhood or special location may be presentedwithin a UI by the messaging client application 104, based ongeolocation information determined by a Global Positioning System (GPS)unit of the client device 102. Another type of filter is a data filter,which may be selectively presented to a sending user by the messagingclient application 104, based on other inputs or information gathered bythe client device 102 during the message creation process. Examples ofdata filters include current temperature at a specific location, acurrent speed at which a sending user is traveling, battery life for aclient device 102, or the current time.

Other annotation data that may be stored within the image table 308 areaugmented reality content items (e.g., corresponding to applying Lensesor augmented reality experiences). An augmented reality content item maybe a real-time special effect and sound that may be added to an image ora video.

As described above, augmented reality content items, overlays, imagetransformations, AR images and similar terms refer to modifications thatmay be made to videos or images. This includes real-time modificationwhich modifies an image as it is captured using a device sensor and thendisplayed on a screen of the device with the modifications. This alsoincludes modifications to stored content, such as video clips in agallery that may be modified. For example, in a device with access tomultiple augmented reality content items, a user can use a single videoclip with multiple augmented reality content items to see how thedifferent augmented reality content items will modify the stored clip.For example, multiple augmented reality content items that applydifferent pseudorandom movement models can be applied to the samecontent by selecting different augmented reality content items for thecontent. Similarly, real-time video capture may be used with anillustrated modification to show how video images currently beingcaptured by sensors of a device would modify the captured data. Suchdata may simply be displayed on the screen and not stored in memory, orthe content captured by the device sensors may be recorded and stored inmemory with or without the modifications (or both). In some systems, apreview feature can show how different augmented reality content itemswill look within different windows in a display at the same time. Thiscan, for example, enable multiple windows with different pseudorandomanimations to be viewed on a display at the same time.

Data and various systems using augmented reality content items or othersuch transform systems to modify content using this data can thusinvolve detection of objects (e.g., faces, hands, bodies, cats, dogs,surfaces, objects, etc.), tracking of such objects as they leave, enter,and move around the field of view in video frames, and the modificationor transformation of such objects as they are tracked. In variousembodiments, different methods for achieving such transformations may beused. For example, some embodiments may involve generating athree-dimensional mesh model of the object or objects, and usingtransformations and animated textures of the model within the video toachieve the transformation. In other embodiments, tracking of points onan object may be used to place an image or texture (which may be twodimensional or three dimensional) at the tracked position. In stillfurther embodiments, neural network analysis of video frames may be usedto place images, models, or textures in content (e.g., images or framesof video). An augmented reality content items thus refer both to theimages, models, and textures used to create transformations in content,as well as to additional modeling and analysis information needed toachieve such transformations with object detection, tracking, andplacement.

Real-time video processing can be performed with any kind of video data(e.g., video streams, video files, etc.) saved in a memory of acomputerized system of any kind. For example, a user can load videofiles and save them in a memory of a device, or can generate a videostream using sensors of the device. Additionally, any objects can beprocessed using a computer animation model, such as a human's face andparts of a human body, animals, or non-living things such as chairs,cars, or other objects.

In some embodiments, when a particular modification is selected alongwith content to be transformed, elements to be transformed areidentified by the computing device, and then detected and tracked ifthey are present in the frames of the video. The elements of the objectare modified according to the request for modification, thustransforming the frames of the video stream. Transformation of frames ofa video stream can be performed by different methods for different kindsof transformation. For example, for transformations of frames mostlyreferring to changing forms of object's elements characteristic pointsfor each of element of an object are calculated (e.g., using an ActiveShape Model (ASM) or other known methods). Then, a mesh based on thecharacteristic points is generated for each of the at least one elementof the object. This mesh used in the following stage of tracking theelements of the object in the video stream. In the process of tracking,the mentioned mesh for each element is aligned with a position of eachelement. Then, additional points are generated on the mesh. A first setof first points is generated for each element based on a request formodification, and a set of second points is generated for each elementbased on the set of first points and the request for modification. Then,the frames of the video stream can be transformed by modifying theelements of the object on the basis of the sets of first and secondpoints and the mesh. In such method, a background of the modified objectcan be changed or distorted as well by tracking and modifying thebackground.

In one or more embodiments, transformations changing some areas of anobject using its elements can be performed by calculating ofcharacteristic points for each element of an object and generating amesh based on the calculated characteristic points. Points are generatedon the mesh, and then various areas based on the points are generated.The elements of the object are then tracked by aligning the area foreach element with a position for each of the at least one element, andproperties of the areas can be modified based on the request formodification, thus transforming the frames of the video stream.Depending on the specific request for modification properties of thementioned areas can be transformed in different ways. Such modificationsmay involve: changing color of areas; removing at least some part ofareas from the frames of the video stream; including one or more newobjects into areas which are based on a request for modification; andmodifying or distorting the elements of an area or object. In variousembodiments, any combination of such modifications or other similarmodifications may be used. For certain models to be animated, somecharacteristic points can be selected as control points to be used indetermining the entire state-space of options for the model animation.

In some embodiments of a computer animation model to transform imagedata using face detection, the face is detected on an image with use ofa specific face detection (e.g., Viola-Jones). Then, an Active ShapeModel (ASM) algorithm is applied to the face region of an image todetect facial feature reference points.

In other embodiments, other methods and algorithms suitable for faceand/or object detection can be used. For example, in some embodiments,features are located using a landmark which represents a distinguishablepoint present in most of the images under consideration. For faciallandmarks, for example, the location of the left eye pupil may be used.In an initial landmark is not identifiable (e.g., if a person has aneyepatch), secondary landmarks may be used. Such landmark identificationprocedures may be used for any such objects. In some embodiments, a setof landmarks forms a shape. Shapes can be represented as vectors usingthe coordinates of the points in the shape. One shape is aligned toanother with a similarity transform (allowing translation, scaling, androtation) that minimizes the average Euclidean distance between shapepoints. The mean shape is the mean of the aligned training shapes.

In some embodiments, a search for landmarks from the mean shape alignedto the position and size of the face determined by a global facedetector is started. Such a search then repeats the steps of suggestinga tentative shape by adjusting the locations of shape points by templatematching of the image texture around each point and then conforming thetentative shape to a global shape model until convergence occurs. Insome systems, individual template matches are unreliable and the shapemodel pools the results of the weak template matchers to form a strongeroverall classifier. The entire search is repeated at each level in animage pyramid, from coarse to fine resolution.

Embodiments of a transformation system can capture an image or videostream on a client device (e.g., the client device 102) and performcomplex image manipulations locally on the client device 102 whilemaintaining a suitable user experience, computation time, and powerconsumption. The complex image manipulations may include size and shapechanges, emotion transfers (e.g., changing a face from a frown to asmile), state transfers (e.g., aging a subject, reducing apparent age,changing gender), style transfers, graphical element application, andany other suitable image or video manipulation implemented by aconvolutional neural network that has been configured to executeefficiently on the client device 102.

In some example embodiments, a computer animation model to transformimage data can be used by a system where a user may capture an image orvideo stream of the user (e.g., a selfie) using a client device 102having a neural network operating as part of a messaging clientapplication 104 operating on the client device 102. The transform systemoperating within the messaging client application 104 determines thepresence of an object (e.g., a face) within the image or video streamand provides modification icons associated with a computer animationmodel to transform image data, or the computer animation model can bepresent as associated with an interface described herein. Themodification icons include changes which may be the basis for modifyingthe user's face within the image or video stream as part of themodification operation. Once a modification icon is selected, thetransform system initiates a process to convert the image of the user toreflect the selected modification icon (e.g., generate a smiling face onthe user). In some embodiments, a modified image or video stream may bepresented in a graphical user interface displayed on the mobile clientdevice as soon as the image or video stream is captured and a specifiedmodification is selected. The transform system may implement a complexconvolutional neural network on a portion of the image or video streamto generate and apply the selected modification. That is, the user maycapture the image or video stream and be presented with a modifiedresult in real time or near real time once a modification icon has beenselected. Further, the modification may be persistent while the videostream is being captured and the selected modification icon remainstoggled. Machine taught neural networks may be used to enable suchmodifications.

In some embodiments, the graphical user interface, presenting themodification performed by the transform system, may supply the user withadditional interaction options. Such options may be based on theinterface used to initiate the content capture and selection of aparticular computer animation model (e.g., initiation from a contentcreator user interface). In various embodiments, a modification may bepersistent after an initial selection of a modification icon. The usermay toggle the modification on or off by tapping or otherwise selectingthe face being modified by the transformation system and store it forlater viewing or browse to other areas of the imaging application. Wheremultiple faces are modified by the transformation system, the user maytoggle the modification on or off globally by tapping or selecting asingle face modified and displayed within a graphical user interface. Insome embodiments, individual faces, among a group of multiple faces, maybe individually modified or such modifications may be individuallytoggled by tapping or selecting the individual face or a series ofindividual faces displayed within the graphical user interface.

As mentioned above, the video table 310 stores video data which, in oneembodiment, is associated with messages for which records are maintainedwithin the message table 314. Similarly, the image table 308 storesimage data associated with messages for which message data is stored inthe entity table 302. The entity table 302 may associate variousannotations from the annotation table 312 with various images and videosstored in the image table 308 and the video table 310.

The augmented reality content items table 316 stores an indication(e.g., a list) of augmented reality content items available forselection and activation by the messaging client application 104. In oneor more embodiments, each augmented reality content item in theaugmented reality content items table 316 is associated with one or moreobject attributes. Each augmented reality content item in the augmentedreality content items table 316 may also be associated with one or morepredefined words (e.g., using metadata labels, designations, and thelike). In one or more embodiments, the messaging client application 104searches the object attributes and/or predefined words stored in theaugmented reality content items table 316 to identify one or moreaugmented reality content items associated with a scanned object or anobject identified in a captured image. Each augmented reality contentitem stored in the augmented reality content items table 316 includesone or more graphical elements or virtual objects which may or may notbe animated. Each augmented reality content item also includesinstructions on where to position the graphical elements or virtualobjects relative to other objects depicted in the captured image.

A story table 306 stores data regarding collections of messages andassociated image, video, or audio data, which are compiled into acollection (e.g., a Story or a gallery). The creation of a particularcollection may be initiated by a particular user (e.g., each user forwhich a record is maintained in the entity table 302). A user may createa “personal Story” in the form of a collection of content that has beencreated and sent/broadcast by that user. To this end, the UI of themessaging client application 104 may include an icon that isuser-selectable to enable a sending user to add specific content to hisor her personal Story.

A collection may also constitute a “live Story,” which is a collectionof content from multiple users that is created manually, automatically,or using a combination of manual and automatic techniques. For example,a “live Story” may constitute a curated stream of user-submitted contentfrom various locations and events. Users whose client devices havelocation services enabled and are at a common location event at aparticular time may, for example, be presented with an option, via a UIof the messaging client application 104, to contribute content to aparticular live Story. The live Story may be identified to the user bythe messaging client application 104 based on his or her location. Theend result is a “live Story” told from a community perspective.

A further type of content collection is known as a “location Story,”which enables a user whose client device 102 is located within aspecific geographic location (e.g., on a college or university campus)to contribute to a particular collection. In some embodiments, acontribution to a location Story may require a second degree ofauthentication to verify that the end user belongs to a specificorganization or other entity (e.g., is a student on the universitycampus).

FIG. 4 is a schematic diagram illustrating a structure of a message 400,according to some embodiments, generated by a messaging clientapplication 104 for communication to a further messaging clientapplication 104 or the messaging server application 114. The content ofa particular message 400 is used to populate the message table 314stored within the database 122, accessible by the messaging serverapplication 114. Similarly, the content of a message 400 is stored inmemory as “in-transit” or “in-flight” data of the client device 102 orthe application server 112. The message 400 is shown to include thefollowing components:

-   -   A message identifier 402: a unique identifier that identifies        the message 400.    -   A message text payload 404: text, to be generated by a user via        a user interface of the client device 102 and that is included        in the message 400.    -   A message image payload 406: image data, captured by a camera        component of a client device 102 or retrieved from a memory        component of a client device 102, and that is included in the        message 400.    -   A message video payload 408: video data, captured by a camera        component or retrieved from a memory component of the client        device 102 and that is included in the message 400.    -   A message audio payload 410: audio data, captured by a        microphone or retrieved from a memory component of the client        device 102, and that is included in the message 400.    -   Message annotations 412: annotation data (e.g., filters,        stickers or other enhancements) that represents annotations to        be applied to message image payload 406, message video payload        408, or message audio payload 410 of the message 400.    -   A message duration parameter 414: parameter value indicating, in        seconds, the amount of time for which content of the message        (e.g., the message image payload 406, message video payload 408,        message audio payload 410) is to be presented or made accessible        to a user via the messaging client application 104.    -   A message geolocation parameter 416: geolocation data (e.g.,        latitudinal and longitudinal coordinates) associated with the        content payload of the message. Multiple message geolocation        parameter 416 values may be included in the payload, each of        these parameter values being associated with respect to content        items included in the content (e.g., a specific image within the        message image payload 406, or a specific video in the message        video payload 408).    -   A message story identifier 418: identifier values identifying        one or more content collections (e.g., “Stories”) with which a        particular content item in the message image payload 406 of the        message 400 is associated. For example, multiple images within        the message image payload 406 may each be associated with        multiple content collections using identifier values.    -   A message tag 420: each message 400 may be tagged with multiple        tags, each of which is indicative of the subject matter of        content included in the message payload. For example, where a        particular image included in the message image payload 406        depicts an animal (e.g., a lion), a tag value may be included        within the message tag 420 that is indicative of the relevant        animal. Tag values may be generated manually, based on user        input, or may be automatically generated using, for example,        image recognition.    -   A message sender identifier 422: an identifier (e.g., a        messaging system identifier, email address, or device        identifier) indicative of a user of the client device 102 on        which the message 400 was generated and from which the message        400 was sent.    -   A message receiver identifier 424: an identifier (e.g., a        messaging system identifier, email address, or device        identifier) indicative of a user of the client device 102 to        which the message 400 is addressed.

The contents (e.g., values) of the various components of message 400 maybe pointers to locations in tables within which content data values arestored. For example, an image value in the message image payload 406 maybe a pointer to (or address of) a location within an image table 308.Similarly, values within the message video payload 408 may point to datastored within a video table 310, values stored within the messageannotations 412 may point to data stored in an annotation table 312,values stored within the message story identifier 418 may point to datastored in a story table 306, and values stored within the message senderidentifier 422 and the message receiver identifier 424 may point to userrecords stored within an entity table 302.

FIG. 5 is a schematic diagram illustrating an access-limiting process500, in terms of which access to content (e.g., an ephemeral message502, and associated multimedia payload of data) or a content collection(e.g., an ephemeral message group 504) may be time-limited (e.g., madeephemeral).

An ephemeral message 502 is shown to be associated with a messageduration parameter 506, the value of which determines an amount of timethat the ephemeral message 502 will be displayed to a receiving user ofthe ephemeral message 502 by the messaging client application 104. Inone embodiment, an ephemeral message 502 is viewable by a receiving userfor up to a maximum of 10 seconds, depending on the amount of time thatthe sending user specifies using the message duration parameter 506.

The message duration parameter 506 and the message receiver identifier424 are shown to be inputs to a message timer 512, which is responsiblefor determining the amount of time that the ephemeral message 502 isshown to a particular receiving user identified by the message receiveridentifier 424. In particular, the ephemeral message 502 will only beshown to the relevant receiving user for a time period determined by thevalue of the message duration parameter 506. The message timer 512 isshown to provide output to a more generalized ephemeral timer system202, which is responsible for the overall timing of display of content(e.g., an ephemeral message 502) to a receiving user.

The ephemeral message 502 is shown in FIG. 5 to be included within anephemeral message group 504 (e.g., a collection of messages in apersonal Story, or an event Story). The ephemeral message group 504 hasan associated group duration parameter 508, a value of which determinesa time-duration for which the ephemeral message group 504 is presentedand accessible to users of the messaging system 100. The group durationparameter 508, for example, may be the duration of a music concert,where the ephemeral message group 504 is a collection of contentpertaining to that concert. Alternatively, a user (either the owninguser or a curator user) may specify the value for the group durationparameter 508 when performing the setup and creation of the ephemeralmessage group 504.

Additionally, each ephemeral message 502 within the ephemeral messagegroup 504 has an associated group participation parameter 510, a valueof which determines the duration of time for which the ephemeral message502 will be accessible within the context of the ephemeral message group504. Accordingly, a particular ephemeral message group 504 may “expire”and become inaccessible within the context of the ephemeral messagegroup 504, prior to the ephemeral message group 504 itself expiring interms of the group duration parameter 508. The group duration parameter508, group participation parameter 510, and message receiver identifier424 each provide input to a group timer 514 which operationallydetermines, firstly, whether a particular ephemeral message 502 of theephemeral message group 504 will be displayed to a particular receivinguser and, if so, for how long. Note that the ephemeral message group 504is also aware of the identity of the particular receiving user as aresult of the message receiver identifier 424.

Accordingly, the group timer 514 operationally controls the overalllifespan of an associated ephemeral message group 504, as well as anindividual ephemeral message 502 included in the ephemeral message group504. In one embodiment, each and every ephemeral message 502 within theephemeral message group 504 remains viewable and accessible for atime-period specified by the group duration parameter 508. In a furtherembodiment, a certain ephemeral message 502 may expire, within thecontext of ephemeral message group 504, based on a group participationparameter 510. Note that a message duration parameter 506 may stilldetermine the duration of time for which a particular ephemeral message502 is displayed to a receiving user, even within the context of theephemeral message group 504. Accordingly, the message duration parameter506 determines the duration of time that a particular ephemeral message502 is displayed to a receiving user, regardless of whether thereceiving user is viewing that ephemeral message 502 inside or outsidethe context of an ephemeral message group 504.

The ephemeral timer system 202 may furthermore operationally remove aparticular ephemeral message 502 from the ephemeral message group 504based on a determination that it has exceeded an associated groupparticipation parameter 510. For example, when a sending user hasestablished a group participation parameter 510 of 24 hours fromposting, the ephemeral timer system 202 will remove the relevantephemeral message 502 from the ephemeral message group 504 after thespecified 24 hours. The ephemeral timer system 202 also operates toremove an ephemeral message group 504 either when the groupparticipation parameter 510 for each and every ephemeral message 502within the ephemeral message group 504 has expired, or when theephemeral message group 504 itself has expired in terms of the groupduration parameter 508.

In certain use cases, a creator of a particular ephemeral message group504 may specify an indefinite group duration parameter 508. In thiscase, the expiration of the group participation parameter 510 for thelast remaining ephemeral message 502 within the ephemeral message group504 will determine when the ephemeral message group 504 itself expires.In this case, a new ephemeral message 502, added to the ephemeralmessage group 504, with a new group participation parameter 510,effectively extends the life of an ephemeral message group 504 to equalthe value of the group participation parameter 510.

Responsive to the ephemeral timer system 202 determining that anephemeral message group 504 has expired (e.g., is no longer accessible),the ephemeral timer system 202 communicates with the messaging system100 (and, for example, specifically the messaging client application104) to cause an indicium (e.g., an icon) associated with the relevantephemeral message group 504 to no longer be displayed within a userinterface of the messaging client application 104. Similarly, when theephemeral timer system 202 determines that the message durationparameter 506 for a particular ephemeral message 502 has expired, theephemeral timer system 202 causes the messaging client application 104to no longer display an indicium (e.g., an icon or textualidentification) associated with the ephemeral message 502.

FIG. 6 is an interaction diagram illustrating a process 600 fornavigating through the display of augmented reality content items (e.g.,corresponding to augmented reality experiences), in accordance with someexample embodiments. For explanatory purposes, the process 600 isprimarily described herein with reference to the messaging clientapplication 104 of the client device 102, and the messaging serversystem 110 of FIG. 1. However, one or more blocks (or operations) of theprocess 600 may be performed by one or more other components, and/or byother suitable devices. Further for explanatory purposes, the blocks ofthe process 600 are described herein as occurring in serial, orlinearly. However, multiple blocks of the process 600 may occur inparallel. In addition, the blocks of the process 600 need not beperformed in the order shown and/or one or more blocks of the process600 need not be performed and/or can be replaced by other operations.

As described herein, the messaging client application 104 is configuredto provide for navigating/scrolling through augmented reality contentitems (e.g., corresponding to augmented reality experiences). Forexample, the messaging client application 104 displays a carouselinterface with icons for selecting from available augmented realitycontent items. The messaging client application 104 receives user input(e.g., a drag gesture) indicating to more quickly navigate between theaugmented reality content items. In response, the messaging clientapplication 104 discontinues displaying the carousel interface (e.g., byreplacing it with a sliding interface), and provides for more quicklynavigating through the augmented reality content items while continuingto display the image data captured by the device camera.

Thus, following start block 602, the messaging client application 104displays image data captured by a camera of the client device 102 and acarousel interface (block 604). For example, the messaging clientapplication 104 is configured to default to activating the camera whenthe messaging client application 104 is initialized. Alternatively or inaddition, the messaging client application 104 automatically activatesthe camera for particular interfaces of the messaging client application104, such as an interface for generating multimedia content (e.g., forincluding in a message). As noted, the carousel interface provides forselecting an augmented reality content item (e.g., or augmented realityexperience) and/or switching between available augmented reality contentitems. The available augmented reality content items may be displayed ina ranked order within the carousel interface.

As noted above, the augmented reality system 124 included in themessaging server system 110 is configured to provide for rankingavailable augmented reality content items. For example, availableaugmented reality content items are ranked by comparing one or moreattributes of object(s) detected in images with corresponding augmentedreality content item attributes/words (e.g., as stored in the augmentedreality content items table 316). Moreover, in case multiple augmentedreality content items are available for a detected object (e.g., auser's face), augmented reality content items may be ranked based on oneor more parameters such as preferences/history of augmented realitycontent items selected by the user, popularity of augmented realitycontent items among system users, newly-available augmented realitycontent items, and the like.

The messaging server system 110 may provide an indication of the rankingto the messaging client application 104. Based on the ranking, themessaging client application 104 may select a default augmented realitycontent item for applying to the captured image (e.g., to displayaugmented reality content with the image) and/or arrange the carouselinterface icons (e.g., representing respective augmented reality contentitems) in ranked order.

The messaging client application 104 receives user input for navigatingthrough available augmented reality content items (block 606). In one ormore embodiments, the messaging client application 104 provides for auser to select to navigate through (e.g., scroll through) the availableaugmented reality content items of the carousel interface. As describedherein, the user may select to navigate through augmented realitycontent items in different manners (e.g., at different speeds) based ondifferent types of gestures.

In one or more implementations, the messaging client application 104 inconjunction with an operating system of the client device 102 (e.g.,operating system 1012, discussed below) is configured to detectdifferent types of user gestures with respect to user input. Forexample, the messaging client application 104 is configured to detectand distinguish between a swipe gesture and a drag gesture, each ofwhich occurs when a finger is moved across the screen (e.g., in ahorizontal or vertical direction).

In one or more implementations, the speed of finger movement across thescreen is used to distinguish between a swipe gesture and a draggesture. For example, a drag gesture is typically slower and morecontrolled than a swipe gesture. On the other hand, a swipe gesture istypically faster than a drag gesture. In one or more implementations, adrag gesture may continue to be detected/processed while the fingermaintains contact with the screen, even when the user switches directionof finger movement across the screen (e.g., from the left-rightdirection to the right-left direction). On the other hand, the swipegesture may simply be completed based a finger moving a thresholdspeed/distance on the screen.

Thus, at decision block 608, the messaging client application 104determines whether the user input corresponds to a first type of gesture(e.g., the drag gesture). For example, the drag gesture (e.g., the morecontrolled and/or slow gesture) corresponds with user intent to morequickly navigate/scroll through the display of available augmentedreality content items (e.g., while still displaying images captured bythe device camera). Thus, the messaging client application 104 navigatesthrough the augmented reality content items at a first speed (block616), which is quicker than the second speed discussed below.

In one or more implementations, the quick navigation/scrolling throughof augmented reality content items (e.g., augmented reality experiences)is effected by accessing representations of augmented reality contentitems in local memory of the client device 102, as opposed to remotelyaccessing augmented reality content item data from the messaging serversystem 110. For example, the local representations for augmented realitycontent items may correspond to one or more images for each augmentedreality content item (e.g., and an order of the augmented realitycontent items), without necessarily including additional augmentedreality content item data such as models, textures and/or other imagesfor transforming image content. In one or more implementations, thelocally-stored representations are accessed by the messaging clientapplication 104 and locally stored prior to displaying the carouselinterface (e.g., upon initialization of the messaging client application104). By virtue of storing the local representations and order of theaugmented reality content items, it is possible for the messaging clientapplication 104 to more quickly navigate/scroll through the display ofavailable augmented reality content items during the drag gesture. It isnoted displaying the augmented reality content items in this manner maynot correspond with fully applying the augmented reality content items,but instead with providing a quick preview of the augmented realitycontent item.

As noted above, a drag gesture continues to be detected when the userswitches direction of finger movement across the screen. Thus, in one ormore implementations, the messaging client application 104 provides fornavigating/scrolling through the augmented reality content items in amanner that corresponds to the drag gesture movement. For example, themessaging client application 104 provides for adjusting the speed ofnavigating/scrolling through the augmented reality content items, tocorrelate with the speed of the finger movement across the devicescreen.

As discussed further below with respect to the example of FIGS. 7A-7B,the messaging client application 104 may be configured to omit displayof the carousel interface during the drag gesture, and to display asliding interface in lieu of the carousel interface. For example, thesliding interface may correspond to a line/bar element that indicates aposition of a current augmented reality content item with respect to theordered list of available augmented reality content items. The positionmay be indicated by an icon, presented on the line/bar element, thatrepresents the current augmented reality content item. In this regard,the locally-stored representations of the augmented reality contentitems may further include the icon data for quick access by themessaging client application 104. Moreover, the locally-storedrepresentations of the augmented reality content items may include aname for each augmented reality content item, for quick access anddisplay by the messaging client application 104 during the dragoperation. Thus, at block 618, the messaging client application 104replaces the carousel interface with the sliding interface.

Upon detecting a release of the finger from the screen, the messagingclient application 104 may request remaining augmented reality contentitem data (e.g., the entirety of the augmented reality content itemdata, including models/textures) from the messaging server system 110.In this manner, with respect to a current augmented reality content itemof the sliding interface, the messaging client application 104 fullyapplies the augmented reality content item to transform the imagecaptured by the device camera, and may revert to displaying the carouselinterface instead of the sliding interface.

At decision block 610, in a case where the user input received at block606 does not correspond to the first type of gesture (e.g., a draggesture), the messaging client application 104 determines whether theuser input corresponds to a second type of gesture (e.g., a swipegesture, corresponding to quicker finger movement relative to the draggesture). If the user input corresponds to the second type of gesture,the messaging client application 104 navigates through the availableaugmented reality content items at a second speed, which is slower thanthe first speed as discussed above (block 612).

In one or more implementations, the slower navigation/scrolling throughof augmented reality content items corresponds with iterating throughavailable augmented reality content items on a per-swipe basis. Forexample, each swipe gesture (e.g., in the left or right direction) mayprovide for the messaging client application 104 to iterate to the nextaugmented reality content item (e.g., in the respective left or rightdirection).

In one or more embodiments, the slower navigation/scrolling through ofaugmented reality content items corresponds with remotely accessing eachaugmented reality content item from the messaging server system 110 inresponse to a swipe gesture. For example, the messaging server system110 requests the respective images, models and/or textures from themessaging server system 110, in order to transform the image captured bythe device camera and fully apply the respective augmented realitycontent items. Moreover, as discussed further below with respect toFIGS. 8A-8B, the messaging client application 104 continues to displaythe carousel interface (block 614). The process ends at end block 620.

Thus, the process 600 provides for the messaging client application 104to more quickly navigate through available augmented reality contentitems, for example, in response to a drag gesture. Alternatively or inaddition, the process 600 provides for the messaging client application104 to more slowly and iteratively navigate through available augmentedreality content items, for example, in response to individual swipegestures.

FIGS. 7A-7C illustrate a user interface 702 for navigating through thedisplay of augmented reality content items (e.g., augmented realityexperiences) based on user input corresponding to a first gesture type,in accordance with some example embodiments. The user interface 702 isdisplayed within the messaging client application 104. For example, FIG.7A corresponds with receiving user input corresponding to the firstgesture type (e.g., a drag gesture), FIG. 7B corresponds with quicklynavigating through augmented reality content items during a drag motionfrom the left-right direction, and FIG. 7C corresponds with quicklynavigating through augmented reality content items when the drag gestureswitches to the right-left direction.

In the example of FIG. 7A, the user interface 702 includes capturedimage data 704 corresponding to image data captured by a front-facingcamera of the client device 102. Alternatively, the image data may becaptured by a rear-facing camera of the client device 102.

The user interface 702 includes a carousel interface 718 which allowsthe user to cycle through and/or select an augmented reality contentitem to apply with respect to the captured image data 704. Each of theavailable augmented reality content items is represented by an iconwhich is user-selectable for switching to the respective augmentedreality content item. In one or more embodiments, the icon correspondingto the active augmented reality content item (e.g., selected augmentedreality content item icon 720) is displayed in a different mannerrelative to (e.g., larger than) the remaining icons. As noted above, theactive augmented reality content item may correspond to a defaultaugmented reality content item selected by the messaging clientapplication 104 based on augmented reality content item ranking datareceived from the messaging server system 110. In one or moreembodiments, user selection of the selected augmented reality contentitem icon 720 provides for generating a message which includes an image(e.g., in response to a press/tap gesture of the selected augmentedreality content item icon 720) and/or a video (e.g., in response to apress-and-hold gesture of the selected augmented reality content itemicon 720) of the screen content, for example, to send to friends,include in a Story, and the like.

In the example of FIG. 7A, the user provides touch input 706corresponding to a first gesture type (e.g., a drag gesture). Forillustrative purposes, an arrow is depicted with respect to the touchinput 706, indicating finger movement from the left-right direction. Inresponse to the touch input 706, the messaging client application 104navigates/scrolls through display of augmented reality content itemsduring the drag gesture. For example, while FIG. 7A illustrates anaugmented reality content item 708 corresponding to a first activeaugmented reality content item, FIG. 7B illustrates an augmented realitycontent item 710 corresponding to a second available augmented realitycontent item.

While not shown in FIGS. 7A-7C, it is noted that additional augmentedreality content items may have been presented in between FIG. 7A andFIG. 7B in response to the touch input 706 (e.g., drag gesture). Forexample, at least the augmented reality content item corresponding toaugmented reality content item 712 in FIG. 7C was presented during thenavigating/scrolling through available augmented reality content items,as it appears in the ordered list of augmented reality content itemsbefore the augmented reality content item corresponding to augmentedreality content item 710.

As noted above, the augmented reality content item 710 may correspond toa locally-stored representation of the augmented reality content item,for example, to quickly navigate/scroll through available augmentedreality content items during the drag gesture. In addition, thelocally-stored representation may include an augmented reality contentitem name 714.

As seen in FIG. 7B, the user interface 702 further includes a slidinginterface 722 which replaces display of the carousel interface 718. Thesliding interface indicates the position of a current augmented realitycontent item (e.g., depicted by the current augmented reality contentitem icon 724) relative to other available augmented reality contentitems.

As discussed above, the messaging client application 104 is configuredto continually process the drag gesture while the finger maintainsscreen contact, even in case where finger movement across the screenchanges direction. In the example of FIG. 7B, the touch input 706changes from the left-right direction to the right-left direction, asdepicted by the arrow corresponding to the touch input 706 in FIG. 7B.In response to the changed direction of the touch input 706, themessaging client application 104 provides for navigating/scrollingthrough the available augmented reality content items in the reverseorder. As shown in the example of FIG. 7C, the messaging clientapplication 104 navigates/scrolls back to the augmented reality contentitem corresponding to the augmented reality content item 712, anddisplays a corresponding augmented reality content item name 716together with a current augmented reality content item icon 726.

FIGS. 8A-8B illustrates a user interface 802 for navigating through thedisplay of augmented reality content items (e.g., augmented realityexperiences) based on user input corresponding to a second gesture type,in accordance with some example embodiments. The user interface 802 isdisplayed within the messaging client application 104. For example, FIG.8A corresponds with receiving user input corresponding to the secondgesture type (e.g., a swipe gesture), and FIG. 8B corresponds withnavigating through augmented reality content items in a more slow,iterative manner.

In the example of FIG. 8A, the user interface 802 includes capturedimage data 804 corresponding to image data captured by a front-facingcamera of the client device 102. Alternatively, the image data may becaptured by a rear-facing camera of the client device 102.

The user interface 802 includes a carousel interface 812 which allowsthe user to cycle through and/or select an augmented reality contentitem to apply with respect to the captured image data 804. Each of theavailable augmented reality content items is represented by an iconwhich is user-selectable for switching to the respective augmentedreality content item. In one or more embodiments, the icon correspondingto the active augmented reality content item (e.g., selected augmentedreality content item icon 814) is displayed in a different mannerrelative to (e.g., larger than) the remaining icons. As noted above, theactive augmented reality content item may correspond to a defaultaugmented reality content item selected by the messaging clientapplication 104 based on augmented reality content item ranking datareceived from the messaging server system 110. In one or moreembodiments, user selection of the selected augmented reality contentitem icon 814 provides for generating a message which includes an image(e.g., in response to a press/tap gesture of the selected augmentedreality content item icon 814) and/or a video (e.g., in response to apress-and-hold gesture of the selected augmented reality content itemicon 814) of the screen content, for example, to send to friends,include in a Story, and the like.

In the example of FIG. 8A, the user provides touch input 806corresponding to the second gesture type (e.g., a swipe gesture). Forillustrative purposes, an arrow is depicted with respect to the touchinput 706, indicating finger movement from the right-left direction. Inresponse to the touch input 706, the messaging client application 104iteratively navigates/scrolls through available augmented realitycontent items. As noted above, a single swipe gesture may cause themessaging client application 104 to iterate to a single, next availableaugmented reality content item (e.g., corresponding to augmented realitycontent item 810 and selected augmented reality content item icon 816 inFIG. 8B), such that navigating through multiple augmented realitycontent items requires respective multiple swipe gestures. Moreover, asnoted above, each of the augmented reality content item 808 and theaugmented reality content item 810 may correspond with respectiverequest by the messaging client application 104 to the messaging serversystem 110 to apply the respective augmented reality content item.

FIG. 9 is a flowchart illustrating a process for navigating through thedisplay of augmented reality content items, in accordance with someexample embodiments. For explanatory purposes, the process 900 isprimarily described herein with reference to the messaging clientapplication 104 and the messaging server system 110 of FIG. 1. However,one or more blocks (or operations) of the process 900 may be performedby one or more other components, and/or by other suitable devices.Further for explanatory purposes, the blocks of the process 900 aredescribed herein as occurring in serial, or linearly. However, multipleblocks of the process 900 may occur in parallel. In addition, the blocksof the process 900 need not be performed in the order shown and/or oneor more blocks of the process 900 need not be performed and/or can bereplaced by other operations.

The messaging client application 104 running on the client device 102displays a carousel interface comprising multiple icons, each iconcorresponding to a respective one of a plurality of augmented realitycontent items (e.g., corresponding to selected augmented reality contentitem(s)) for displaying with an image captured by a device camera (block902). Each icon of the carousel interface may be selectable by a userfor displaying the respective one of the plurality of augmented realitycontent items with the image.

The messaging client application 104 receives user input to navigatethrough display of the plurality of augmented reality content items(e.g., augmented reality content items) while displaying the image(block 904). In a case where the user input corresponds to a predefinedtype of gesture, the messaging client application 104 navigates throughdisplay of the plurality of augmented reality content items whiledisplaying the image (block 906), and omits display of the carouselinterface (block 908).

The predefined type of gesture may be a drag gesture. In a case wherethe user input corresponds to a second predefined type of gesture (e.g.,a swipe gesture), the messaging client application 104 navigates throughdisplay of the plurality of augmented reality content items whiledisplaying both the image and the carousel interface. Navigating throughdisplay of the plurality of augmented reality content items with respectto the drag gesture may be performed at a first speed (e.g., faster orquicker speed), and the navigating through display of the plurality ofaugmented reality content items with respect to the swipe gesture may beperformed at a second speed (e.g., a slower speed).

The messaging client application 104 may receive, from a messagingserver system 110, representations of the plurality of augmented realitycontent items (e.g., augmented reality content items), and store therepresentations in local memory. Navigating through display of theplurality of augmented reality content items may include retrieving therepresentations from the local memory, and navigating through display ofthe representations while displaying the image.

The plurality of augmented reality content items may be arranged inorder, where navigating through display of the plurality of augmentedreality content items is based on the order. In a case where the userinput corresponds to the predefined type of gesture (e.g., the draggesture), the messaging client application 104 may display a slidinginterface in lieu of the carousel interface, the sliding interfaceindicating a position of a currently-displayed augmented reality contentbased on the order.

FIG. 10 is a block diagram 1000 illustrating a software architecture1004, which can be installed on any one or more of the devices describedherein. The software architecture 1004 is supported by hardware such asa machine 1002 that includes processors 1020, memory 1026, and I/Ocomponents 1038. In this example, the software architecture 1004 can beconceptualized as a stack of layers, where each layer provides aparticular functionality. The software architecture 1004 includes layerssuch as an operating system 1012, libraries 1010, frameworks 1008, andapplications 1006. Operationally, the applications 1006 invoke API calls1050 through the software stack and receive messages 1052 in response tothe API calls 1050.

The operating system 1012 manages hardware resources and provides commonservices. The operating system 1012 includes, for example, a kernel1014, services 1016, and drivers 1022. The kernel 1014 acts as anabstraction layer between the hardware and the other software layers.For example, the kernel 1014 provides memory management, processormanagement (e.g., scheduling), component management, networking, andsecurity settings, among other functionality. The services 1016 canprovide other common services for the other software layers. The drivers1022 are responsible for controlling or interfacing with the underlyinghardware. For instance, the drivers 1022 can include display drivers,camera drivers, BLUETOOTH® or BLUETOOTH® Low Energy drivers, flashmemory drivers, serial communication drivers (e.g., Universal Serial Bus(USB) drivers), WI-FI® drivers, audio drivers, power management drivers,and so forth.

The libraries 1010 provide a low-level common infrastructure used by theapplications 1006. The libraries 1010 can include system libraries 1018(e.g., C standard library) that provide functions such as memoryallocation functions, string manipulation functions, mathematicfunctions, and the like. In addition, the libraries 1010 can include APIlibraries 1024 such as media libraries (e.g., libraries to supportpresentation and manipulation of various media formats such as MovingPicture Experts Group-4 (MPEG4), Advanced Video Coding (H.264 or AVC),Moving Picture Experts Group Layer-3 (MP3), Advanced Audio Coding (AAC),Adaptive Multi-Rate (AMR) audio codec, Joint Photographic Experts Group(JPEG or JPG), or Portable Network Graphics (PNG)), graphics libraries(e.g., an OpenGL framework used to render in two dimensions (2D) andthree dimensions (3D) in a graphic content on a display), databaselibraries (e.g., SQLite to provide various relational databasefunctions), web libraries (e.g., WebKit to provide web browsingfunctionality), and the like. The libraries 1010 can also include a widevariety of other libraries 1028 to provide many other APIs to theapplications 1006.

The frameworks 1008 provide a high-level common infrastructure that isused by the applications 1006. For example, the frameworks 1008 providevarious graphical user interface (GUI) functions, high-level resourcemanagement, and high-level location services. The frameworks 1008 canprovide a broad spectrum of other APIs that can be used by theapplications 1006, some of which may be specific to a particularoperating system or platform.

In an example embodiment, the applications 1006 may include a homeapplication 1036, a contacts application 1030, a browser application1032, a book reader application 1034, a location application 1042, amedia application 1044, a messaging application 1046 (e.g.,corresponding to the messaging client application 104), a gameapplication 1048, and a broad assortment of other applications such asthird-party applications 1040. The applications 1006 are programs thatexecute functions defined in the programs. Various programming languagescan be employed to create one or more of the applications 1006,structured in a variety of manners, such as object-oriented programminglanguages (e.g., Objective-C, Java, or C++) or procedural programminglanguages (e.g., C or assembly language). In a specific example, thethird-party applications 1040 (e.g., applications developed using theANDROID™ or IOS™ software development kit (SDK) by an entity other thanthe vendor of the particular platform) may be mobile software running ona mobile operating system such as IOS™, ANDROID™, WINDOWS® Phone, oranother mobile operating system. In this example, the third-partyapplications 1040 can invoke the API calls 1050 provided by theoperating system 1012 to facilitate functionality described herein.

A “client device” refers to any machine that interfaces to acommunications network to obtain resources from one or more serversystems or other client devices. A client device may be, but is notlimited to, a mobile phone, desktop computer, laptop, portable digitalassistants (PDAs), smartphones, tablets, ultrabooks, netbooks, laptops,multi-processor systems, microprocessor-based or programmable consumerelectronics, game consoles, set-top boxes, or any other communicationdevice that a user may use to access a network.

A “communication network” refers to one or more portions of a networkthat may be an ad hoc network, an intranet, an extranet, a virtualprivate network (VPN), a local area network (LAN), a wireless LAN(WLAN), a wide area network (WAN), a wireless WAN (WWAN), a metropolitanarea network (MAN), the Internet, a portion of the Internet, a portionof the Public Switched Telephone Network (PSTN), a plain old telephoneservice (POTS) network, a cellular telephone network, a wirelessnetwork, a Wi-Fi® network, another type of network, or a combination oftwo or more such networks. For example, a network or a portion of anetwork may include a wireless or cellular network and the coupling maybe a Code Division Multiple Access (CDMA) connection, a Global Systemfor Mobile communications (GSM) connection, or other types of cellularor wireless coupling. In this example, the coupling may implement any ofa variety of types of data transfer technology, such as Single CarrierRadio Transmission Technology (1×RTT), Evolution-Data Optimized (EVDO)technology, General Packet Radio Service (GPRS) technology, EnhancedData rates for GSM Evolution (EDGE) technology, third GenerationPartnership Project (3GPP) including 3G, fourth generation wireless (4G)networks, Universal Mobile Telecommunications System (UMTS), High SpeedPacket Access (HSPA), Worldwide Interoperability for Microwave Access(WiMAX), Long Term Evolution (LTE) standard, others defined by variousstandard-setting organizations, other long-range protocols, or otherdata transfer technology.

A “component” refers to a device, physical entity, or logic havingboundaries defined by function or subroutine calls, branch points, APIs,or other technologies that provide for the partitioning ormodularization of particular processing or control functions. Componentsmay be combined via their interfaces with other components to carry outa machine process. A component may be a packaged functional hardwareunit designed for use with other components and a part of a program thatusually performs a particular function of related functions. Componentsmay constitute either software components (e.g., code embodied on amachine-readable medium) or hardware components. A “hardware component”is a tangible unit capable of performing certain operations and may beconfigured or arranged in a certain physical manner. In various exampleembodiments, one or more computer systems (e.g., a standalone computersystem, a client computer system, or a server computer system) or one ormore hardware components of a computer system (e.g., a processor or agroup of processors) may be configured by software (e.g., an applicationor application portion) as a hardware component that operates to performcertain operations as described herein. A hardware component may also beimplemented mechanically, electronically, or any suitable combinationthereof. For example, a hardware component may include dedicatedcircuitry or logic that is permanently configured to perform certainoperations. A hardware component may be a special-purpose processor,such as a field-programmable gate array (FPGA) or an applicationspecific integrated circuit (ASIC). A hardware component may alsoinclude programmable logic or circuitry that is temporarily configuredby software to perform certain operations. For example, a hardwarecomponent may include software executed by a general-purpose processoror other programmable processor. Once configured by such software,hardware components become specific machines (or specific components ofa machine) uniquely tailored to perform the configured functions and areno longer general-purpose processors. It will be appreciated that thedecision to implement a hardware component mechanically, in dedicatedand permanently configured circuitry, or in temporarily configuredcircuitry (e.g., configured by software), may be driven by cost and timeconsiderations. Accordingly, the phrase “hardware component” (or“hardware-implemented component”) should be understood to encompass atangible entity, be that an entity that is physically constructed,permanently configured (e.g., hardwired), or temporarily configured(e.g., programmed) to operate in a certain manner or to perform certainoperations described herein. Considering embodiments in which hardwarecomponents are temporarily configured (e.g., programmed), each of thehardware components need not be configured or instantiated at any oneinstance in time. For example, where a hardware component comprises ageneral-purpose processor configured by software to become aspecial-purpose processor, the general-purpose processor may beconfigured as respectively different special-purpose processors (e.g.,comprising different hardware components) at different times. Softwareaccordingly configures a particular processor or processors, forexample, to constitute a particular hardware component at one instanceof time and to constitute a different hardware component at a differentinstance of time. Hardware components can provide information to, andreceive information from, other hardware components. Accordingly, thedescribed hardware components may be regarded as being communicativelycoupled. Where multiple hardware components exist contemporaneously,communications may be achieved through signal transmission (e.g., overappropriate circuits and buses) between or among two or more of thehardware components. In embodiments in which multiple hardwarecomponents are configured or instantiated at different times,communications between such hardware components may be achieved, forexample, through the storage and retrieval of information in memorystructures to which the multiple hardware components have access. Forexample, one hardware component may perform an operation and store theoutput of that operation in a memory device to which it iscommunicatively coupled. A further hardware component may then, at alater time, access the memory device to retrieve and process the storedoutput. Hardware components may also initiate communications with inputor output devices, and can operate on a resource (e.g., a collection ofinformation). The various operations of example methods described hereinmay be performed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implementedcomponents that operate to perform one or more operations or functionsdescribed herein. As used herein, “processor-implemented component”refers to a hardware component implemented using one or more processors.Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method may be performed by one or more processors orprocessor-implemented components. Moreover, the one or more processorsmay also operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an API). The performance ofcertain of the operations may be distributed among the processors, notonly residing within a single machine, but deployed across a number ofmachines. In some example embodiments, the processors orprocessor-implemented components may be located in a single geographiclocation (e.g., within a home environment, an office environment, or aserver farm). In other example embodiments, the processors orprocessor-implemented components may be distributed across a number ofgeographic locations.

The terms “machine-readablemedium,” “computer-readable medium” and “device-readable medium” meanthe same thing and may be used interchangeably in this disclosure.

An “ephemeral message” refers to a message that is accessible for atime-limited duration. An ephemeral message may be a text, an image, avideo and the like. The access time for the ephemeral message may be setby the message sender. Alternatively, the access time may be a defaultsetting or a setting specified by the recipient. Regardless of thesetting technique, the message is transitory.

A “machine-storage medium” refers to a single or multiple storagedevices and/or media (e.g., a centralized or distributed database,and/or associated caches and servers) that store executableinstructions, routines and/or data.

A processor may,for example, be a Central Processing Unit (CPU), a Reduced InstructionSet Computing (RISC) processor, a Complex Instruction Set Computing(CISC) processor, a Graphics Processing Unit (GPU), a Digital SignalProcessor (DSP), an Application Specific Integrated Circuit (ASIC), aRadio-Frequency Integrated Circuit (RFIC) or any combination thereof. Aprocessor may further be a multi-core processor having two or moreindependent processors (sometimes referred to as “cores”) that mayexecute instructions contemporaneously.

A “signal medium” refers to any intangible medium that is capable ofstoring, encoding, or carrying the instructions for execution by amachine and includes digital or analog communications signals or otherintangible media to facilitate communication of software or data. Theterm “signal medium” shall be taken to include any form of a modulateddata signal, carrier wave, and so forth. The term “modulated datasignal” means a signal that has one or more of its characteristics setor changed in such a matter as to encode information in the signal. Theterms “transmission medium” and “signal medium” mean the same thing andmay be used interchangeably in this disclosure.
